REVOLVING VENTILATING-FAN.

Specification of Letters Patent.

Patented May 28, 1918..

Application filed July 13, 1916. Serial No. 109,146.

To all whom it may concern:

Be it lmown that I, HERBERT I. FINCH, a citizen of the United States,residing at the city of St. Louis, State of Missouri, have invented acertain new and useful Improvement in Revolving Ventilating-Fans, ofwhich the following is a full, clear, and exact description, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, formingpart of this specification.

This invention relates to improvements in electrically operated rotaryfans of the type wherein one or more fans with independent motors arearranged for revolution about a mounting or support for the purpose ofdistributing the fans influence. The revolution of fans of thischaracter has been obtained in different fashions, most commonly throughthe reaction of the fan blades upon the air. It is the principal purposeof my invention to provide a novel revolving fan construction whereinthe revolution o f the fan is obtained by a special form of drivingmechanism which is actuated by one of the fan motors.

A further objectof my invention is to provide a form of mechanismwhereby this result is obtained, and wherein the fan together with itsactuating motor is adjustable to difierent angles relative to thesupport about which it revolves.

A further object of my invention is to provide a mechanism which willsecure the operative revolution of the fan at a speed which will beconstantly in definite predetermined proportion to the speed ofoperation of the fan motor and which, by virtue of that fact, can beaccurately controlled as to speed of operation.

A further object of my invention is to provide a fan constructionwherein a plurality of fans are driven each by its individual motor, themotors being independently adjustable to different inclinations and allof the motors being revolved about a supporting member by power derivedfrom one of the fan motors.

A still further object of my invention is to provide a constructionwhich will secure acontinuous and thorough lubrication of the operatingparts upon the actuation of the revolving mechanism.

Another object is to improve generally upon the construction of fans ofthis character with the purpose of providing a sim ple, strong, durable,economical and easily adjusted apparatus.

Other and further objects will be obvious or pointed out hereinafter.

In the accompanying drawings, I have shown for the purpose ofillustration one form of my invention embodied in a ceiling fan, thatis, a form in which the device is arranged to be supported from above,as from a ceiling. It is obvious, however, that the invention -may alsobe embodied in a structure designed to be sup orted upon a column, or inother suitable ashions.

In the embodiment herein. i1lustrated Figure 1 represents a sideelevation of the device; l

Referring to the various parts by means of the reference numerals, itwill be understood that 1 represents a supporting connection which mayalso form an outlet conduit for the electrical wiring. Supported thereonand secured thereto by suitable means 2, is a pedestal member 4. Thispedestal member includes the socket portion 5, which engages thesupporting member 1, the cover plate 6, which extends annularly from thesocket member, the bearing portions 7 and 7 5 which form a sleeve-likemember extending axially fromv the socket and cover CQUS'E iiteriim r "ftiiig i n r i; tiicloscenti ,i th

Iii he caseof the arm 11;; which is ztence this adjustment is 1 the movehiiity ofthe rei tive to the fiieti nmochite any desired c to tive tc the axis of5 the Irame and thence up to the chamber 19. When the mechanism is atrest the lubricant Will feed downwardly through the spiral groove fromthe chamber 49. Inasmuch as the contact of the housing portions 26 uponthe annular flanges 20 forms a completely inclosed chamber about thegearing, all working parts will be subjected to thorough lubricationwithout opportunity for the escape of the lubricant.

The current is supplied to the motors 31 in any suitable fashion. Thatshown comprises the slip rings 50 suitably insulated and mounted on theupper portion of the rotary frame member, and brushes 51 arranged tocooperate therewith and mounted in the cover plate 6. From the collectorrings 50, the wires 4.4 lead down to the arms 25, and out through thecasing portions 42 to the motors.

In the shaft 34 is arranged a suitable escapement clutch 52 of anysuitable form such as will permit the shaft being uncoupled at will todisconnect the revolving mechanism from the motor, and such as will beoperable by excessive pressure to permit escapement in case therevolving portions should meet with an obstruction. Or a suitable clutch43 may be placed in sleeve 39.

By virtue of the mechanism above described, it will be observed that'therevoluble movement of the fans is derived positively from the fan motor,and may be regulated as to speed by regulation of the speed of the fanmotor. Furthermore, it is to be observed that the fans are adjustableindependently to various angles, without adecting in any fashion theoperation of the rotating mechanism. A neat, compact and substantiallydust-proof mechanism is provided, and thorough lubrication of theworking parts is secured. Suitable mounting. for the switch 17 and thespeed controlling coil 54 is provided. The latch pins 31 are operablefrom the exterior of the casing, so that no dismantling of the device isrequired in order to adjust the fans.

I am aware that my invention is suscepti ble of changes, modifications,and adaptations not herein specifically described or shown, butcomprehended nevertheless within the scope and spirit of my invention asindicated in the following claims.
